Permeability barrier function of skin exposed to ionizing radiation.
OBJECTIVE To characterize the epidermal permeability barrier function of skin during exposure to ionizing radiation. DESIGN A prospective cohort study. SETTING University hospital medical center. PATIENTS Fifteen women receiving local radiation therapy (5000-6000 rad [50-60 Gy]) following breast-conserving surgery for breast cancer. MAIN OUTCOME MEASURES Clinical symptoms and transepide...
متن کاملThematic review series: skin lipids. The role of epidermal lipids in cutaneous permeability barrier homeostasis.
The permeability barrier is required for terrestrial life and is localized to the stratum corneum, where extracellular lipid membranes inhibit water movement. The lipids that constitute the extracellular matrix have a unique composition and are 50% ceramides, 25% cholesterol, and 15% free fatty acids. Essential fatty acid deficiency results in abnormalities in stratum corneum structure function...
متن کاملPsychological stress perturbs epidermal permeability barrier homeostasis: implications for the pathogenesis of stress-associated skin disorders.
BACKGROUND A large number of skin diseases, including atopic dermatitis and psoriasis, appear to be precipitated or exacerbated by psychological stress. Nevertheless, the specific pathogenic role of psychological stress remains unknown. In 3 different murine models of psychological stress, it was recently shown that psychological stress negatively impacts cutaneous permeability barrier function...
متن کاملEffect of "rose essential oil" inhalation on stress-induced skin-barrier disruption in rats and humans.
In stressed animals, several brain regions (e.g., hypothalamic paraventricular nucleus [PVN]) exhibit neuronal activation, which increases plasma adrenocorticotropic hormone (ACTH) and glucocorticoids. We previously reported that so-called "green odor" inhibits stress-induced activation of the hypothalamo-pituitary-adrenocortical axis (HPA axis) and thereby prevents the chronic stress-induced d...
متن کاملEpidermal barrier formation and recovery in skin disorders.
Skin is at the interface between the complex physiology of the body and the external, often hostile, environment, and the semipermeable epidermal barrier prevents both the escape of moisture and the entry of infectious or toxic substances. Newborns with rare congenital barrier defects underscore the skin's essential role in a terrestrial environment and demonstrate the compensatory responses ev...
